New Seco face mill offers flexibility and ease of use

According to Seco Tools, its new-generation Octomill 06 face milling cutter provides improvements to ease-of-use, flexibility and stability. The cutter ensures self-centring of inserts for reliable, error-free positioning and incorporates a multi-insert pocket design that accommodates various insert types for a range of applications.

Easy to use and reliable
Octomill 06 self-centering inserts allow operators to position inserts with high repeatability, quickly and securely. The use of a long insert screw enables insert indexing without having to remove the screw from the cutter body. Notably, the cutter-insert interface design disconnects cutting edges from support surfaces and mimics the design of a double-sided insert while keeping the positive setting approach of a single-sided solution.

“This separation of cutting edges and support surfaces keeps worn portions of the insert from damaging or
negatively impacting the performance of unused edges,” says Seco Product Manager Tobias Jakobi.
“Furthermore, the self-centering feature prevents the occurrence of incorrectly positioned inserts that can
cause instability, edge breakage, tool breakage, costly work interruptions and the need for rework.”

The Octomill 06 is suitable for applications featuring unstable setups or thin-walled parts. Featuring a right-handed design with a straight cutting edge, the cutter incorporates a high helix angle of +16° to reduce radial and axial forces, and enable high-quality production. Seco says the cutter achieves smoother entry and exit, and reduces back-cutting effects. Additionally, Octomill 06 provides consistent wear along the entire
cutting edge.

Flexibility across a range of applications

The multi-insert pocket design of Octomill 06 accommodates face milling, round and moderate high-feed inserts. This capability allows a single cutter body to perform a variety of applications, including face milling,
ramping, helical interpolation and profiling. A diverse range of insert grades and geometries provides high
performance in materials spanning the P, M, K, N, S and H Seco materials groups.
